The technology includes the steps of: associating material-object identification
code identifying each individual material object with material-object information
representing information about material object identified by identification code
and storing identification code and material-object information in material-object
information database in each of business categories; sending code and information
stored in database in each business category; integrating items of information
having same code with each other among codes and items of information received
from database in each business category to generate integrated material-object
information, associating identification code with integrated material-object information
identified by code and storing identification code and integrated material-object
information in integrated database; requesting to send integrated material-object
information associated with given identification code; reading requested integrated
material-object information from integrated database and sending integrated information
to requester of integrated material-object information; and receiving and outputting
sent integrated material-object information.
